TIPS:
Reactive dyes
Cov dyes yog tsim los ntawm cov tshuaj tiv thaiv ntawm dichloro-s-triazine dye nrog ib qho amine ntawm qhov kub thiab txias hauv cheeb tsam ntawm 25-40 ° C, uas ua rau kev hloov pauv ntawm ib qho ntawm cov tshuaj chlorine atoms, ua rau tsis tshua muaj reactive monochloro-s-triazine. (MCT) xim.
Cov dyes yog siv tib yam rau cellulose tshwj tsis yog tias, tsis tshua muaj reactive dua li dichloro-s-triazine dyes, lawv yuav tsum tau kub dua (80 ° C) thiab pH (pH 11) rau fixation ntawm cov xim rau cellulose rau. tshwm sim.
Cov hom dyes no muaj ob lub chromogens thiab ob pawg MCT reactive, yog li ntawd muaj ntau dua substantivity rau cov fiber ntau piv rau cov yooj yim MCT hom dyes.Qhov kev ua kom muaj zog ntxiv no tso cai rau lawv kom ua tiav kev ua haujlwm zoo rau cov fiber ntau ntawm qhov nyiam dyeing kub ntawm 80 ° C, ua rau fixation qhov tseem ceeb ntawm 70-80%.Dyes ntawm hom no yog thiab tseem muaj kev lag luam nyob rau hauv Procion HE ntau ntawm kev ua haujlwm siab dyes.
Cov dyes tau qhia los ntawm Bayer, tam sim no Dystar, nyob rau hauv lub npe Levafix E, thiab yog raws li lub nplhaib quinoxaline (Fig. 1.9).Lawv yog me ntsis reactive thaum piv nrog cov dichloro-s-triazine dyes thiab yog siv nyob rau ntawm 50 ° C, tab sis lawv raug rau hydrolysis nyob rau hauv acidic tej yam kev mob.
